9 = 4
18 = 8
27 = 12
36 = 16
45 = 20
12 people divided by 3 people = 4
so if 2 bowls serve 3 people...2 bowls x 4 = serve 12 people
therefore, 8 bowls serve 12 people
X=3, y=4
x=-2, y=9
Set x equal to anything, then isolate y to get the other number.
Okay, so you know that the perimeter of the pen is 28 feet. Now we need the separate side lengths.
P = 28 ft.
Length = x
Width = (1/2)x + 2
So now we can plug in the little equations of length and width into a perimeter formula:
2(x) + 2((1/2)x + 2) = 28
Distribute the 2's and solve as needed.
2x + x + 4 = 28
3x + 4 = 28
3x = 24
x = 8
To find the width, just plug in 8 for x in our little equation:
(1/2)(8) + 2
= 6
So, the length is 8 feet and the width is 6 feet.
